That means:
A normal amplifier „sees" 4 Ohms as 4 Ohms. In a bridged amplifier, each amplifier „sees" 2 Ohms only! That’s why in bridged mode always
4 Ohms must be maintained although the amplifier might be 2 Ohms stable.
Caution
This product is capable of conducting very high sound pressure levels, and can thus be harmful to your health. Prolonged exposure
to high volume levels can cause hearing loss! Please use restraint on the volume control.
XETEC
wants you to enjoy your amplifier for a long time to come, and we do not take responsibility for hearing loss nor other health
problems.
0. Installation:
For safety reasons, the amplifier has to be mounted properly and fixed to the car’s body. Please fix the device using the screws that come
with your product. Be careful when drilling holes, there might be wires, fuel lines or the gas tank behind a wall! Never drill holes when you
do not know what’s behind. Never install signal wires close to power cables to avoid hum and alternator noise is being induced.
1. Connections:
Before you make any connections, always disconnect the battery!
1.1 First of all, connect the RCA cables coming from the radio/head unit to the respective inputs of your amplifier. Always run signal cables in
a distance to power cables and the vehicle’s factory wires to avoid induction of noise.
1.2 Now the speaker wires must be connected to the respective speaker terminals. Please make sure to use speakers with the correct impe
dance! Also make sure to connect all speakers with correct polarity to avoid phase problems which can spoil the sound of the whole
system.
1.3 Next step is the ground connection. Check for a good grounding point using your vehicle’s chassis. Make sure that this point has good
electrical contact! Some parts of the chassis might only be glued and have no contact to battery (-). Run all ground cables of the system
to this point to avoid alternator whine and other noise.
